Central pulverulent cataract (Coppock cataract)

Abstract

A 60-year-old man presented at Sankara Eye Hospital, Guntur, Andhra Pradesh, with blurring of vision in both eyes of 5 years’ duration. He had no systemic illness. Best-corrected visual acuity was <20/200 in both the eyes. Slit-lamp examination showed clear corneas, round reactive pupils, and age-related nuclear sclerosis associated with a core of central discoid opacity, with scattered dots in the center of both eyes. Slit-lamp photographs of the cataract with diffuse illumination (A) and in cross section (B) show the central, discoid opacity; the distinct borders of the cataract, with scattered dotlike opacities visible on retroillumination (C), are clinically suggestive of a central pulverulental cataract, or Coppock cataract.
